COLLAPSIBLE CONTAINER.

Application filed October 14, 1927. Serial No. 226,190.

The present invention relates to collapsible containers and has for its object to provide a container of this character which may be collapsed by degrees and which will be positively held against accidental collaps- Another object is to provide a container of this character in which the contents are prevented from working out between the collapsible members.

Other objects are simplicity of construction and operationand cheapness of manufacture.

Other objects and advantages will appear from the following description and will be set forth in the subjoined claims, and I do not wish to be limited in the scope of my invention except as I shall be limited by said claims.

In the drawings:

Figure 1 is a longitudinal section through the can on the line 11 of Figure 3.

Figure 2 is a longitudinal section through the can on the line 22 of Figure 1.

Figure 3 is a cross section of the can on the line 3-3 of Figure 1, showing the relation of the two spaced walls at the lower end of the can.

Referring to the drawings in detail, it will be observed that'the can is made up of two telescoping members and 11, the latter comprising inner and outer walls 12 and 13, the wall 13 being unobstructed throughout its height and the wall 12 having ridges 14 alternating with depressions 15. The inner wall is preferably made of resilient material so as to give under pressure and the upper wall 10 is provided with a beaded lower end 16, the bead on which is adapted to ride in the space between the walls 12 and 13 and to fit snugly in the depressions 15 and between the inner and outer walls. The upper ends of the walls 12 and 13 are provided with beads 17 and 18, the former lying entirely in the space between the walls 12 and 13 in order to prevent the flow of the contents of the can, while the latter lies partially between said walls and partially on the outside of the walls 13.

The upper end of the member 10 is also so provided with a ridge 19 circumferentially thereof and adapted when the telescoping members are fully collapsed to rest on the bead 18, preventing further progress of the upper member into the can. The walls 12 and 13 are connected to the bottom 20 in any suitable manner. The outer wall, as shown, is connected by bending the bottom member over a laterally extending rib 21 formed on the wall 13, while the inner wall may be soldered or otherwise secured thereto. The box may be also provided with any sort of covering, as shown at 22.

Having described my invention, what I claim is:

1. A collapsible container comprising telescoping members, one of said telesc0p-- ing members bein formed with two spaced concentric walls, t e other telescoping member being of such dimensions as to make it slidable between said walls and means formed on the lower edge of the last mentioned telescopic member andbeing engageable in spaced depressions formed in one of the walls of the first mentioned members to adjustably and telescopically supportthe members in cooperative association with each other.

2.. A collapsible-container comprising two telescoping tubular members, one of said members consisting of spaced concentric walls, one of said walls having alternate ridges and depressions formed thereon, the other of said telescoping members having a head on its lower end adapted to ride bcs5 tween said concentric walls and to fit snugly in said depressions.

In testimony whereof I afiix my signature.
